Software testing ppt
- 2. TESTING • In general, testing is finding out how well something works. In terms of human beings, testing tells what level of knowledge or skill has been acquired. • In computer hardware and software development, testing is used at key checkpoints in the overall process to determine whether objectives are being met.
- 3. 1. Ensures accountability for a given task 2. Clearly list the responsibilities for various functions to various people. so that everyone knows his or her work fits into entire project. 3. Complement each other, ensuring no one steps on others 4. Supplement each other so that no task is let unassigned. RESPONSIBILITIES WHILE TESTING
- 4. o WHAT IS SOFTWARE TESTING • Software testing is a process of executing a program or application with the intent of finding the software bugs.
- 5. Software testing is a process that should be done during the development process. And those process are: : • Verification is the process to make sure the product satisfies the condition imposed at the start of the development phase. In other words, to make sure the product behaves the way we want it to. • Validation is the process to make sure the product satisfies the specified requirements at the end of the development phase. In other words, to make sure the product is built as per customer requirements.
- 6. WHY SOFTWARE TESTING IS NEEDED? 1.)Software testing is really required to point out the defects and errors that were made during the development phases. 2.)It’s essential since it makes sure of the Customer’s reliability and their satisfaction in the application. 3.)It is very important to ensure the Quality of the product. 4.)It is important to ensure that the application should not result into any failures 5.) Testing is required for an effective performance of software application or product.
- 7. The student will be able to: 1. Understand the impact of software bugs and importance of software testing 2. Develop skills to find out bugs in any type of software 3. Use your new testing skills to test not just the software, but also product specification the raw code, and even the user's manual 4. Learn how to test software for compatibility, usability and cultural issues 5. Discover how to improve your testing efficiency by automating your test.
- 8. SOFTWARE QUALITY ASSURANCE AND QUALITY CONTROL (SQA and SQC)
- 9. SOFTWARE QUALITY ASSURANCE It is error preventive and verification activity. the SQA role is to observe that documented standard, process and procedures are followed as enforced by development policy. Required material is checklist and performed by QA engineers.
- 10. SOFTWARE QUALITY CONTROL It is defect detection and validation activity. SQC role is to validate the quality of a system and to check whether this application adheres the defined qualities standard or not. Required material is application and performed by software tester.
- 11. SDLC The software development lyf cycle It is essentially a series of a steps or phases that provide a model for the development and the management of the software.
- 12. steps involve in SDLC Requirement analysis project planning project design development testing implementation maintainence
- 14. STLC Every organization has their own predefined STLC steps in order to make a quality application that help them to adhere standard quality it also have some phased like in SDLC
- 17. White Box Testing • Done by Developers. • It tests the working of applications
- 18. Black Box Testing • Done by Testers. • It tests the functionality of application without peering into its working. • Internal behavior of the code is unknown.
- 19. Grey Box Testing
- 20. Developer vs Tester • Developer always wants to see his code working properly. • Tester will test the application, make it fail in any way, and then surely will test how application is not working correctly.
